call jbpm workflow from jboss portal
It's possible to create a jbpm object from a portlet?
In the method doView from my file, i've created an jbpm object. Although, i get an exception when i run the code. Here is the file and the exception:
import java.io.*;
import javax.portlet.*;
//import com.sample.WorkFlow;
public class Registo extends GenericPortlet {
public WorkFlow workflow;
String filename = "simple.par/processdefinition.xml";
public static final boolean DEBUG = true;
public void doView(RenderRequest request, RenderResponse response)
throws PortletException, IOException
{
response.setContentType("text/html");
String jspName = getPortletConfig().getInitParameter("jspView");
PortletRequestDispatcher rd = getPortletContext().getRequestDispatcher("/WEB-INF/jsp/RegistoOcorrencia.jsp");
rd.include(request, response);
if(DEBUG)
{
System.out.println("xxxxxxxxxxxxxxxxxxxxxxxxx");
System.out.println("JANELA 1");
System.out.println(jspName);
System.out.println("xxxxxxxxxxxxxxxxxxxxxxxxx");
}
workflow = new WorkFlow(filename);
// Realiza o primeiro estado
//workflow.RegistoOcorrenciaTask(workflow.getTaskInstance());
}
}
